Product information

Description

The Cooler Master MWE Gold 1250 V2 is a fully modular ATX 3.1 power supply unit delivering 1250 W of continuous power for high-end desktop systems. It is 100% ATX 3.1 compatible, supports the 12V-2x6 connector specification, and is designed to supply peak power demands of modern graphics cards and complete PC builds. The unit includes a 24-pin ATX motherboard connector, multiple SATA cable lengths, and comes in a black finish.

Advantages

The MWE Gold 1250 V2 holds an 80 PLUS Gold certification, ensuring around 90% efficiency at typical load. It uses a 140 mm fan with a fluid-dynamic bearing and Smart Thermal Control (STCM) so the fan remains off until roughly 40% load for reduced noise. The unit is rated to operate safely in ambient temperatures up to 50 °C and features fully modular flat black cables for improved cable management, airflow, and a cleaner interior appearance.

Suitable for

  • High-end gaming PCs with RTX 40-series or similar GPUs
  • Overclocked systems and performance workstations
  • Custom builds requiring modular cabling and strong peak power delivery

Key specifications

  • Total power: 1250 W
  • Efficiency: 80 PLUS Gold (~90% typical)
  • ATX standard: ATX 3.1 compatible
  • Motherboard connector: 24-pin ATX
  • Fan diameter: 140 mm, fluid-dynamic bearing
  • Operating ambient temperature: up to 50 °C
  • Product colour: Black
  • Weight: 3.02 kg

How to use

Install the MWE Gold 1250 V2 into a standard ATX-compatible case following the motherboard and PSU orientation guidelines. Connect the 24-pin ATX cable to the motherboard, attach the appropriate PCIe 12V-2x6 (and additional) power connectors to your GPU(s), and use SATA or peripheral cables for drives and accessories as required. Only attach modular cables that are needed for your configuration to maintain optimal airflow and cable management.

Usage recommendations

Ensure your system's power requirements, including peak GPU draw, are within the 1250 W capacity. Allow sufficient case ventilation, keep cable runs tidy using the modular cables provided, and refer to Cooler Master’s PSU calculator or product documentation when sizing a PSU for complex multi-GPU or heavily overclocked systems.
